I have a problem where I can't even install the game. It installs normally (yet slowly) but when it gets to the end of the fourth disc it has an error that says
Feature Transfer Error

Feature: Starwars Knights of the old Republic II:The Sith Lords_Files

Component: Default Component

File: E:\data5.cab

Error: Data Error(cyclic redundancy check)

After this it just sits there for about 5 minutes then quits out of the installation like nothing happened. I tried setting the compatibility to xp like it says in the first post and I'm running the setup as an administrator but I still can't install the game.
